I have a problem in SIM detection in SIM 900 module. When I insert SIM in the SIM card holder, sometimes it detects SIM for 10-15 times (i decide the SIM detection by the blinking of LED and time it takes to blink again) and then it doesn't detect the SIM. Till now the method I adopted was that I plugged out the SIM 900 module and plug in the power again. In this case also, some times it detects, may be for 1-2 hours. After that it doesn't detect the SIM. Please help me in the issue.
